FWIW, here is the alignment of init_thread_info on all architectures: alpha: 2 * PAGE_SIZE arm, avr32, frv, mn10300, s390, sh, x86: THREAD_SIZE blackfin: THREAD_SIZE, but uses a different section cris, m68k-sun3: PAGE_SIZE h8300, m32r, m68knommu, ppc32, xtensa, m68k-std: 0x2000/8192 ia64: PAGE_SIZE (but ia64 is different) mips: _PAGE_SIZE parisc, ppc64: 16384 ppc32: 8192 um: KERNEL_STACK_SIZE sparc: PAGE_SIZE with .text section sparc64: 16384 (implicit) This is the same as THREAD_SIZE on all architectures, except for mips in certain configurations, which should be fixed. Maybe we can get all of them to just use THREAD_SIZE in there?
